Abhayasutta
Evaṁ me sutaṁ— ekaṁ samayaṁ bhagavā rājagahe viharati gijjhakūṭe pabbate. Atha kho abhayo rājakumāro yena bhagavā tenupasaṅkami; upasaṅkamitvā bhagavantaṁ abhivādetvā ekamantaṁ nisīdi. Ekamantaṁ nisinno kho abhayo rājakumāro bhagavantaṁ etadavoca: “pūraṇo, bhante, kassapo evamāha: ‘natthi hetu, natthi paccayo aññāṇāya adassanāya. Ahetu, appaccayo aññāṇaṁ adassanaṁ hoti. Natthi hetu, natthi paccayo ñāṇāya dassanāya. Ahetu, appaccayo ñāṇaṁ dassanaṁ hotī’ti. Idha bhagavā kimāhā”ti? “Atthi, rājakumāra, hetu, atthi paccayo aññāṇāya adassanāya. Sahetu, sappaccayo aññāṇaṁ adassanaṁ hoti. Atthi, rājakumāra, hetu, atthi paccayo ñāṇāya dassanāya. Sahetu, sappaccayo ñāṇaṁ dassanaṁ hotī”ti.
With Prince Abhaya
So I have heard. At one time the Buddha was staying near Rājagaha, on the Vulture’s Peak Mountain. Then Prince Abhaya went up to the Buddha, bowed, sat down to one side, and said to him: “Sir, Pūraṇa Kassapa says this: ‘There is no cause or reason for not knowing and not seeing. Not knowing and not seeing have no cause or reason. There is no cause or reason for knowing and seeing. Knowing and seeing have no cause or reason.’ What does the Buddha say about this?” “Prince, there are causes and reasons for not knowing and not seeing. Not knowing and not seeing have causes and reasons. There are causes and reasons for knowing and seeing. Knowing and seeing have causes and reasons.”
